LUBRICATOR.

SPECIFICATION forming part oi' Letters Patent No. 337,500, dated March9, 1886.

(No model.)

To all whom it may concern:

Be it known that we, LEOPOLD KAOZANDER, of the city, county, and Stateof New York7 and ROBERT RUDDY, of Mount Vernon, in the county ofVestohester and State of New York,

have invented a certain new and useful Improvement in Lubricators, ofwhich the following is a specification.

Our invention has relation to that class of 1o lubricators (designedmore particularly 4for use with locomotives) in which the oil-cham beris combined with a condensing-chamber in which steam is condensed, andfrom which the resulting water of condensation is caused i 5 to passgradually to the oil-chamber, for the purpose of effecting the feed ofthe lubricant.

The object of our improvement is to bring about a better, speedier, andmore efficient condensation of the steam in the condensing- QO chamber.To this end we combine with the condensingchamber two or moresteam-inlets, which are opposed to one another in the sense that thejets issuing from t-hem will meet or strike against one another with theresult of dispersing and scattering the steam throughout the condensingchamber and over or against the interior wall thereof, and thuseffecting a very rapid and thorough condensa` tion.

The nature of our improvement and the manner in which the same is or maybe carried into effect will readily be understood by reference to theaccompanying drawings, in which we have represented ourinvention appliedto a lubricator of the kind shown and described in Letters Patent N o.324,339, granted to us on the 11th of August, 1885.

In the drawings, Figure l is a vertical central section on line l l,Fig. 3. Fig. 2 is a ver- .io tical central section on line 2 2, Fig. 3.Fig. 3 is a section on line 3 3, Fig. l, omitting the valve forcontrolling the escape of the condense-water and the sight-feed glassand its connections. Fig. 4 illustrates the manner of applying ourimproved lubricator in order to insure in the condenser steam -jetsdischarging therein from opposite directions. The

lubricator itself is represented in elevation, while the bottomconnections (which in this condenser.

instance are those of the ordinary tallow-cup 5o in use for many yearspast) are in'section.

` Ve will first give a general description of the lubricator, and willthen point out the features which characterize our improvements.

F is the oil-chamber; A, the main steamconduit; B, the verticalsteam-channel; C, the condenser; D, the extension of channel B.

H J K L are the parts by which the water of condensation is fed from thecondenser to the oil-chamber.

E is the sight-feed glass.

G P O are the sight-feed-glass connections.

I is the nozzle.

N is the oil-feed pipe, leading from the upper part of the oil-chamberto the lower connection, O.

S is the steam-valve, and T the draw-off cock or Valve.

The parts thus far named in their general arrangement and mode ofoperation resemble like lettered parts in Letters Patent No. 324,339,and to this extent require no further explanation here. The constructionand arrangement of the channel-extension D and of the condenser are,however, somewhat modilied, so as to introduce therein the featureswhich characterize our present improvement, andV these features we shallnow proceed to describe. The steam-pipe D extends, as usual, from thechamber B to the upper part of the Opposite its upper end we place theinlet of a second steam pipe, p, which is to be connected to the sourceof steam-supply, and should of course be provided at a suitable orconvenient point with a controlling-valve.

In practice we propose to connect the pipe with the dome or otherelevated steam space of the boiler of the locomotive. The steamjetsissuing from the two pipes D and p meet near the top of the condenser,with the effect of scattering and dispersing the steam against the wallsthereof, and thus effecting a rapid and thorough condensation.

To receive the pipe 1J, We form on the top of condenser anexternally-screw-threaded neck, n, to receive the union coupling u,which holds in place upon the neck the tail-piece t, to which the pipe pis made fast by a screw-joint or otherwise. It will be noted that thetop pipe, t, under this arrangement does not itself enter the condenserproper. It will also be noted that as both steam-jets enter the condenser under the same pressure, no steam entering at the top of thecondenser from the pipe p can pass down into the central pipe, D. It ispreferred to close the top ofthe pipe D, and to provide in said pipeside holes for the lateral discharge of the steam. In this way the jetis deflected laterally and outwardly against the walls of the condenser.This feature is of value, whether the opposite jet from pipe p be usedor not.

XVe have just above said that both steamjets enter the condenser underthe same press'- ure. This is effected by connecting both the topconnection, p, and the steamconduit A to the same source ofsteamsupply-as, for instance, to the boiler or to the steam-pipeat apoint intermediate between the throttle and the steam-inlet, so that thecondenser may be constantly supplied with steam through both pipes p Aat the same pressure, whether steam is cut off from the engine or not.This is illustrated in Fig. 4, where our lubricator screws into the samesocket in which the ordinary tallow-cup has heretofore been screwed, thesocket 1, tallow pipe branch 2, boiler branch 3, and valve 4 being thecustomary and well-known tallow-cup connection which have for many yearsbeen in use. Steam, through the boiler branch 3, (which opens into somehigh part vof the boiler,) passes up into steam'pipeA and theneeto thecondenser. .Atwthe same time, through the top connection, p, which alsois connected to some high part of the boiler, asteam-jet is alsodischarged into the condenser. The prime object of the arrangement is tofurnish a larger and more certain supply oi condense-water, and not inany way to influence the internal pressure of the lubricator or theequalizing of the pressure upon the oil, the action of the steam in therespects last named being precisely the same, Whether the top connectionis used or not.

Having described our improvement and the manner in which the same is ormay be carried into effect, what we claim, and desire to secure byLetters Patent, is as follows:

1. The combination, with the oil and condensing chambers of alubricator, of two steam jets or pipes connected with a source ofcontinuous steamsupply and discharging into the condensing-chamber fromopposite directions, one of said jets or pipes communicating with theoil-discharge passage, substantially as and for the purposeshereinbefore set forth.

2. The combination, with the oil and condensing chambers and theirconnections and the top steam-pipe, p, of the steam-channelB and thecentral steam-pipe, D, extending up into the condensing-chamber andclosed at top, and provided with lateral discharge-holes h, as and forthe purposes hereinbefore set forth.

3. The combination, with the oil and condensing-chambers, thesight-feed, and the oil and water regulating devices, of two steanr jetscommunicating with asource of cont-inuous steam -supply and discharginginto the condenser, entering the one centrally and vertically from thetop and the other centrally and vertically from the bottom ofthecondensing-chamber, the two being arranged so that they shall meet nearthe top ofthe condenser, substantially as and for the purposeshereinbefore set forth.

4. The combination, with the oil and condensing chambers, of the centralsteam-pipe, D, with closed top and lateral openings h, and the opposedsteam-pipe p, substantially as and for the purposes hereinbefore setforth.

5. The combination of the oil-chamber, the condenser-chamber, thesight-feed, and their connections, the conduit-passage up through theoilehamber and discharging into the condenser-chamber, and having abranch leading to the sight-feed glass, whereby said conduit serves atonce for the supply of steam and the discharge of oil, a branch pipefrom said conduit to a source of continuous steanrsupply, and anauxiliary pipe, p, leading into the condenser from the same source ofsteam-supply, these parts being arranged and organized as and for thepurposes hereinbefore set forth.

In testimony whereof we have set ourhands this 9th day of January, A. D.1886.
